  • wedge 121 may include primary wedge 131 and secondary wedge 133.
  • primary wedge 131 may meet secondary wedge 133 at secondary angled surface 135.

Abstract

La présente invention concerne une coulisse automatique pour tuyau comprenant un corps de coulisse pour tuyau comprenant une paroi intérieure de forme généralement tronconique. Une pluralité de coins sont positionnés de façon à coulisser le long de la paroi intérieure conique et peuvent être à entraînement hydraulique. Dans certains modes de réalisation, les coins alternent entre des coins longs et courts, de sorte que seuls les coins longs sont utilisés pour se mettre en prise avec un élément tubulaire présentant un petit diamètre, et qu'à la fois les coins longs et courts sont utilisés pour se mettre en prise avec un élément tubulaire présentant un grand diamètre. Dans certains modes de réalisation, la coulisse automatique pour tuyau peut comprendre un ensemble centreur. Dans certains modes de réalisation, la coulisse automatique pour tuyau peut comprendre un ensemble de balayage.
